Let's denote the number of bookmarks Mark must sell as x.
The cost of the handmade cards is $20.00 each.
The total cost of the bookmarks is $2.50 times the number of bookmarks: $2.50x.
Mark wants his total sales to reach a minimum of $90.00, so the total cost of the handmade cards and bookmarks must be at least $90.00:
20x + 2.50x ≥ 90
Simplifying the equation:
22.5x ≥ 90
Dividing both sides of the equation by 22.5:
x ≥ 90/22.5
Simplifying the right side of the equation:
x ≥ 4
Therefore, Mark must sell at least 4 bookmarks.
The answer is C. x ≥ 16.
